A Application filed November 20, 1914. Serial No. 873,085.

To all 'wflommay concern:

Be it known that I, JOHN F. OComson, a citizen of the-United States,

residing at Chicago, inthe county of Cook and State of Illinois, have invented 'a certain new and useful Improvement in Two-Part Yokes, of

which the following is a full, clear, "concise,

and exact description, rcferencebeing had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in An object of the invention is to provide a yoke consisting of two like parts having in-' tegral means thereon for locking the parts against lateral separation, the interlocking of the partsbeing-eflected by means of tongues and groov I *Theinvention furthermore consists in the 0;

improvements inthe parts and devices and in the novel combinations of the parts and centrally located transversely ofthe rear devices, claimed. 7 I In the drawing forming a part of this specification Figure 1 is a side 'elevationsof a yoke embodying my improvements. "Fig.

2.is a top-plan view of the structure illustratedin'Fig. 1. Fig. 3 is a'vertical sectional view taken substantially ontheline 3-3- of Fig. 1 and Fig. 4-. is a detail side elevationof one of the yoke members and showing the inner side of the filler web "haw ing the interlocking device thereon.

Insaiddrawing, the yoke as shown com-Q prises two like loop .members: H M-10; "eac having upper and'lower army i l-11, rear connecting portion 12 and front sidewall 13, the latter being" provided with an elongated coupler key s lot 14. At its rear end,

each yoke memberis provided'on the inner side thereof with a fillesifiange or web 15 connecting portion 12whicl 1' flange has an enlarged or widened front edge 16 to p'rpvide a suitable bearing. against the rear side of a rear follower. web 15, that is the inner sidewheu the yelie' members are in assembled. relation, is vided two diametrically disposed segmental" 3; Ayoke for draft riggings comprising 100 On the inner side of .the

member 17, as shown in Figs. 3 and 4, is provided with a laterally extending oven hanging segmental flange or tongue 19 which is adapted to be seated in and interlock groove 20 formed in the corresponding mem ber 18 of the other lo op member. In other with a correspondingly undercut segmental words, the overhanging flange or tongue formed on one member 17 of one yoke mem her is adapted to be inserted in the correspondingly shape-d groove or recess in the member 18 of the otheryoke member and the two parts are assembled and self locked by first placing the two yoke members 10-10 at an angle of approximately 45 degreeswto each other, so that the bosses 17 and 18.0f one member willpass into the spaces between the bosses 17 and 18 of the 1 otheryoke member. Thenby swinging the twoyoke members 10 into alinement, it is apparent that the flange 19 of the one will the two yoke members is prevented' If desired, the two webs or flanges 15 may be perforated as indicated at 21 and a rivet 22 passed therethrough to assist in holding the two yoke members together ,and to prevent prising twommber'smavingintegraFine-ans for connecting the same and preventing lat- .i fl lll m ans being.
